As with any disinfection system, maintaining proper residual values is the key to effective pathogen control. 

To facilitate reliable chemical feed control, ATI has developed an on-line water quality monitor cable of providing real time measurement of low levels of PAA in solution. 

The Q45-85 Peracetic Acid Monitor uses a direct sensing polarographic probe. 

The probe is typically used in a flowcell, but a submersible sensor is also available. 

A permeable diffusion membrane isolates the sensing electrodes from the measured sample, providing long-term stability without electrode fouling problems. 

The measurement is selective for PAA and is not affected by changes in hydrogen peroxide concentration, which is always present in PAA solutions.
Features
  • Programmable range options from 0-2 PPM up to 0-200 PPM provide maximum application flexibility. AC Power Options:
  • Power options include 115/230 Vac. Analog Output Options:
  • Two isolated 4-20 mA outputs are standard. Default setting provides Analog outputs for PAA and temperature. PID Output:
  • Standard PID control function assignable to one Analog output. Relay Outputs:
  • Two SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Flexible Mounting:
  • NEMA 4X (IP-66) enclosure is suitable for wall, pipe, or panel mounting. Clear Display:
  • Back-lit large LCD display provides clear visibility in any lighting conditions. A scrolling second line on the display provides additional information and programming prompts.
